... 3) można spotkać wczesną wiosną po zimie na plantacjach cebuli ozimej wysiewnej około połowy sierpnia, na których bezpośrednio po siewie stosowano herbicydy zawierające pendimetalinę (np. Stomp 330 EC, Panida 330 EC) nie niszczące tego chwastu i po wschodach cebuli w okresie letnio-jesiennym, gdy nie stosowano dodatkowo innych herbicydów (Dobrzański i Pałczyński 2005). Starcowi mogą towarzyszyć w dużej ilości gatunki średniowrażliwe na pendimetalinę (rumianowate, chaber bławatek , tobołki polne, mlecz zwyczajny), a więc nie w każdych warunkach zwalczane skutecznie. ...

... Podleúny et al. (1993), Adamczewski et al. (1988), Rychcik (2005) stress the fact that the effectiveness of weed-killing action of herbicides, although dependent on soil and climatic conditions and the technique and time of the treatment, is very high and necessary in pea agrotechnique. In the study by Anyszka et al. (1999), the effectiveness of applied herbicides (Basagran 600 SL, Barox 460 SL) was high, the weed reduction being estimated within the range 93.4100%. In this investigation, the effectiveness of applied herbicides (Basagran 600 SL and Afalon 50 WP) was evaluated at 100% after the emergence and over 90% before harvest. ...

... The number of chemicals available for weed control in cucumbers has been limited and results with them some times have been erratic. Recommended herbicides in Poland are as follows: naptalam, napropamid and clomazone (Dobrzański et all 1990, Dobrzański & Pałczyński 1995, 1998 Pałczyński & Dobrzański 2000). Crop resistance to herbicides depend on several factors, among them genetic are very important. ...

... Czeczko and Mikos-Bielak [31] observed that spraying plants with Asahi at a concentration of 0.1% significantly increased the yield of leek, celeriac, and potato. Similarly, Dobrzański et al. [39] reported a positive impact of this preparation on the yield of onion. Asahi (0.1%) and Tytanit (0.05%) preparations were found to enhance the marketable yield of carrot roots by reducing the share of small and unmarketable roots in the total yield [40]. ...

... Onion is a weak competitor with weeds [4] due to a slow seedling emergence and establishment rate [1], and its shoot architecture is of thin vertical leaves that do not produce much shade throughout the growing season [5]. It has been shown that season-long infestation of annual weeds, such as lambsquarters (Chenopodium album L.), can result in >90% yield reduction, with 43% reduction observed when weeds remain untreated during the seedling establishment stage [6]. Thus, developing efficient and sustainable weed management for onion, mainly during early growth stages, is essential to ensure high yields [7]. ...
